copy and replace files on SCCM client

Hello - What is the best way to copy and replace file on SCCM client which are windows 2003 and windows 2008/R2?

I tried to use the vb script but it didnt worked.

Dim objFSO, objFile
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.GetFile("\\sccmtst01.test.edu\DIS\script\replacefile\adnan.txt")
objFSO.CopyFile objFile.Path, "D:\adnancopytest\"
WScript.Echo "Done."

this is what i see on execmgr.log on sccm client
